A high availability solution for the database stack is an important aspect to consider when migrating or deploying Oracle databases in the AWS Cloud to help ensure that the architecture can meet the service level agreement (SLA) of the application. Unavailability of a critical data...
You can create Read Replicas using theRDS APIs, the RDS command-line tools, or theAWS Management Console.If you use the Amazon RDS APIs, you will call theCreateDBInstanceReadReplicaAPI to create a Read Replica from a specified source DB Instance. For a create to succeed, your source DB In...
Aurora can have 15 replicas while MySQL has 5, and the replication process is faster (sub 10 ms replica lag) Failover in Aurora is instantaneous. It’s HA (High Availability) native. Aurora costs more than RDS (20% more) – but is more efficient ...
Isaac Wong is VP of Platform Architecture atMedidata. He told us: Medidata provides a cloud platform for life science companies to design and run clinical trials faster, cheaper, safer, and smarter. We use Amazon RDS to store mission critical clinical development data and tested many data migrat...
Applications must update the connection string to leverage readreplicas RDS Read Replicas - Use Cases You have a production database that is taking on normal load You want to run a reporting application to run some analytics You create a Read Replica to run the new workload there ...

Before a MySQL DB instance can serve as a replication source, we must enable automatic backups on the source DB instance by setting the backup retention period to a value other than 0. This requirement also applies to a Read Replica that is the source DB instance for another Read...
Scalability and Architecture: AWS RDS RDS provides vertical scaling by changing the instance class and horizontal scaling with read replicas. However, RDS doesn’t offer automatic storage scaling or serverless mode like Aurora. Replication: AWS Aurora Aurora supports up to 15 read replicas, with sub...
